DESCRIPTION:The current generation of Cosmic Microwave Background experime
 nts are measuring fluctuations on a few arcminute scales. To convincingly 
  constrain early universe physics from the Silk damping tail we have to un
 derstand the foreground emission from distant dusty star forming galaxies:
  the Cosmic Infrared Background.  In the last few years there has been sig
 nificant progress in measuring the clustering power of the CIB\, both from
  new microwave data\, and from observations in the infrared by BLAST and H
 erschel. We show how a simple template fits Herschel\, Planck\, and BLAST 
 CIB power spectra\, and can be used to model contamination for CMB experim
 ents. By combining the angular power spectra with galaxy number counts\, w
 e also show a new model that more fully describes the physical properties 
 of the dusty CIB galaxies. Finally we discuss how our knowledge of the CIB
  affects current constraints on the kinetic Sunyaev Zel'dovich effect from
  patchy reionization.
